    Re: need help understanind my dyno sheet

    the temps per the dyno machine were 99.92 on the 291 run --- 105.46 on the 279 run and 105.22 on the 287 run..

    Re: need help understanding my dyno sheet

    i think i figured it out.it looks like the max h.p, numbers are around 7200 rpm..i dont know how usefull that horsepower is way up there...any thoughts please let me know,

    Re: need help understanding my dyno sheet

    From the looks of the chart, it appears that three tests were run to give three different estimates of the horsepower and torque.

    If you have a 997, then your power is down, probably due to the lower octane fuel that is mandated in California.

    Jim this is a chassis dyno that measures Rear Wheel Horsepower not flywheel. His numbers are in line for a 3.6. The issue I have with the dyno is the CF (Correction Factor) is STD non SAE.

    Re: need help understanding my dyno sheet

    carmos, so what kind of modification do you have on your 997 3.6?

    Re: need help understanding my dyno sheet

    hi WR ,well it looks like worst case,5 hp ,best case 10 -12 hp.plus sounds alot better ..total cost 900.00 for revo software,1000.00 for the agency mufflers installed ,95.00 for the k&n filter...so about 2000.00 total..i am happy,with the sound alone,plus it seems to me to run abit better.so i am happy over all,i may install the plenum and see what i get,it looks like 5 to 10 hp for that..so will see.
